Summary

UZUNOV B. A., GÄRTNER G. & STOYNEVA M. P. 2012. Notes on the akinete-forming strain of the green alga Klebsormidium dissectum (Streptophyta) from Pirin Mts., Bulgaria. – Phyton (Horn, Austria) 52 (1): 139–144, with 8 figures.


From the Pirin Mts. National Park in Bulgaria soil samples were investigated for the content of algae. Among them, three species of the streptophyte genus Klebsormidium SILVA, MATTOX & BLACKW. were identified. One strain of Klebsormidium dissectum (GAY) ETTL & GÄRTNER with akinete formation was observed. The term „akinete“ („hypnoblast“) is used because of the inclusion of the original cell wall of the former vegetative cell in the wall of the resting stage. Since the presence of akinetes has been rarely observed in Klebsormidium (or just rarely documented and reported) in the taxonomic literature, their finding is interesting as a documented confirmation of this mode of reproductive- and resting cell formation. Therefore, in the present work, the most characteristic morphological and reproductive features of the studied isolate are presented.
